Question

What does "My natural skill lies in this area" mean?
The context:
  "YOU don't have enough experience or qualifications for this role.What makes you believe you could handle the position?"
   "I'm a fast learner and enjoying learning on the job.My natural skill lies in this area, and I'm confident that I could handle this chanllenge."

Answer

You could change the word "lies" for "is".  The writer says his or her natural skills or abilities match the role.  I would say "skills" rather than "skill".  So for example, if you are a caring person by nature, then you could say your natural skills suit you well for a nursing role.
